Martinez V3 Brushless Gimbal for GoPro Hero3

Helping a friend with his brushless gimbals controller is quite an interesting experience. The board came with pin headers not yet soldered to it place. Searching the internet for information regarding how to connect and how to setup the gimbals itself is a challenge. But i managed at the end to get the right settings for used with a GoPro Hero3 on board. For a new technology, brushless gimbals has come to the point where every one can have a great stable aerial videos.

I am not going for the detail step, but just sharing what i've done.

My DIY Tricopter

 Last couple of years i've tried to build a tricopter base on David's build (rcexplorer.se). At that time flight control boards are still new in developement and the one that proven to work is way to expensive. So we used gyros and mixing in the radio as David did at that time. It is a challenging experience to make it fly and a big satisfactory once it does. Thanks to Myhotgears for sponsoring the build. But now with all the various flight controller available on the market have made flying multirotors a new hobby with growing fans.

KKMulticopter FlyCam Blackboard - Twincopter

A friend of mine gave me his old multirotor flight controller board to play with (thanx Myhotgears). The first thing that came into my mine is build a twin/dual copter out of it. Just to prove the concept and have the feel of it. Further more by the time i got the FC i only have two motors and two esc at hand.
Like i said, i build it just to prove the concept and get the feel of it myself.

LED Navigation Light with ATtiny45/85

Since a friend introduce me to arduino, i has been my dream to build myself a navigation lights customize to my liking.
He who played with arduino longer than me have come out with an on board navigation lights complete with strobe lights, beacon and even capabilities to switch your lights on and off using your remote control.
I think i am far from that, but i have build myself a simple navigation lights with strobe and beacon and i'm using ATtiny45 for its small size.

FPV RC Rover Using Smartphones

I initially built a servo driven RC rover for my son to play with and because i found it to be something i have to try for myself. Who would guess the rover just been driven by two normal 9g servos. Thanks to rctestflight.
I just take it a little bit further by testing it for a ground FPV platform. Inspired by a friend who uses two smartphones as an FPV gear for his quadcopter, i dig out my old Galaxy Ace.

How To - Servo 360 Mod

I get a lot of question as to how i did the servo mod for my rc rover. That is involving modifying a normal 9g servo to be able to turn freely on both direction.
I got the tips from a youtube channel rctestflight which happens to be the same person i got the idea to build the rc rover. The build is really cool (you can ask my son) and the modification needed is simple. Anyone with a spare servo and couple of old broken one could easily make it.

Simple DIY 5V BEC

I'm looking for a way to power my servo tester with my LiPo without using an ESC which i used to do. I don't have a BEC laying around, and i'm too cheap to buy one just to power a servo tester. Then i remember a friend of mine building his own BEC from a minimal amount of component to power his sailboat with a LiPo battery.
I start looking for parts in my workshop to make myself a DIY BEC and lucky me i have some laying around in my electronics box. A couple of hours later after some datasheet reading, schematic figuring, component placing and soldering, i got myself one simple homemade BEC.

My Surmount Face Lift

It has been long since i first set sail with this model sailboat Surmount from HobbyKing. Although i got it as a second hand owner from my fellow rcer who got himself a new and bigger boat. It is fast becoming my favorite model for weekends. Since i got it, i have change the rigging, change the rudder servo and change the jib sail. But a friend of mine who recently bought himself a Surmount has shown me what have he done to his boat, which catch my attention to do something more to my boat.

Servo Driven Rover

The idea was not originally mine as i found it on the youtube, posted by rctestflight on my quest searching something simple for my son to play with. Interesting enough it uses small servos for drive which i have laying around and foam board as the skeletons. Seeing it as a great couple of hour project, i proceed to make it in one afternoon. Here is my way of doing it.

How To - Diy Hinges

Hinges is a must in making your control surfaces working properly. There are many ways of making a hinges on a scratchbuild model aircraft. It is depend on the build material you are using for your build and how strong you want your hinges to hold.
For a basic scratchbuild using compress foam/ foam board, the easiest way is to make a tape hinge. Here i'm going to show you the basic of making a tape hinge for your model aircraft.
